Wayne State University plans within two months to solicit bids for the $5.64 million renovation and expansion of a 32,000-square-foot Cass Avenue building on the Detroit campus, according to John Davis, vice president of finance and facilities and CFO. The Board of Governors last month approved the project which will provide space to consolidate WSU's public safety department from its two current buildings to one site, Davis said. "We still have to come to an agreement as to the overall development," he said, adding there is no deadline for doing so.
